[R] rgl on MacOS Tahoe is not working

[Duncan Murdoch]

No problem.  BTW, advice for anyone who does want to update to Tahoe:

Do a Time Machine backup just before the update.  It is possible to 
revert the update, but it is slow and a little nerve wracking:  it 
involves reformatting your main disk to make it bootable in Sequoia, 
then restoring from the backup.
